Java utilities provide powerful tools that have a wide range of uses and complex functions. However, this complexity calls for a wide range of experience and mastery over the tool for you to be able to use it properly and smoothly. For many, this is acquired only through continued use. The same applies to the display table tag utility used in Java and Matlab, which is far more complex than other table-making productivity software. If you are interested in learning how to use the display table tag, here are some simple guidelines that can get you started.
- Familiarize yourself with the functions. Basically, the display table tag interface is much like the usual Microsoft Excel Table. You need to use your mouse if you needed to change the width of a cell. Double click a cell to change its text content. You can change the many attributes of the table by simply clicking. Shift-clicking or using shift up and down on objects will extend selection
- Get to know the common and most important codes. Java functions mainly on codes, and this feature makes its functioning harder to comprehend. Therefore, you initially need to get to know some of the codes for you to be able to master them. For example, if you wish to change the initial column width, you must call upon the command ‘setPreferredWidth’ on each column. You can then customize it to the type of data that you will input in the next steps.
- Selection methods. It is another necessary knowledge for you to know the selection options apart from using the keyboard and the mouse. In some circumstances, you may need to change your selection settings. There are three settings, “Row Selection”, “Column Selection”, and “Cell Selection”. The type of selection is dictated by the check settings. If all the three selection settings are unchecked, there is no selection being made.
- Create a Table Model. By default, you may use a table model object as an initial table. To create your own show table, you need to create it as a subclass of the AbtractTableModel class.
- Create an SQL query. You need to enter this code, ResultSet rs = conn.createStatement(); st.executeQuery("select Lname from Customers where Snum = 2001");
- Hard at first. It will be relatively hard to follow the steps, but all you need to do is to get to know the necessary codes. Creating a query table is one of the key skills needed in using the display table tag in Java.
- Search the web for more comprehensive tutorials on using the utility and get to know the basic codes and inquiry, especially when you display text and display cells on the display tag. You can learn to add glass in cells, round them up, and perform other actions by checking the Sun Java site if you want to know more about using this utility.
Using a program such as Java may baffle you at first because of the linguistically discriminating jargon which the site uses. Nonetheless, the highly efficient features of the display table tag can undeniably help you in using this wonderful tool in your daily endeavors.
